Kim revealed on Tuesday that her
pregnancy was a 'pleasant surprise' as she suffers from the same
fertility issues as her younger sister Khloe, 28, who has been trying to
get pregnant with her husband Lamar Odom for the past two years.

She said: 'Khloe has been very open about her fertility issues and I think I was always really kind of quiet about mine, and I have similar issues.

'It was a pleasant surprise when so many doctors were telling me one thing and then the opposite happens, and that's just an exciting moment.'

Kim also said she 'definitely' wants
to get married again, despite still being legally married to her
estranged husband Kris Humphries.Though the couple couldn't be happier with their lives at the moment, they want to make their union official in the future.

Speaking
on the 'Today' show, Kim said: '[I'm] so content with how things are
right now. And how life is and we're so happy. We definitely want that
in the future, but I'm not in a rush.'
